CriticalCVSS 9.3 · v2.0—Weaponized No fix recorded

Noroxi assessment

Priority: Plan (action score 55/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 60.1% (FIRST EPSS); higher than 99.1% of all records.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Integer signedness error in Apple QuickTime before 7.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PnSize opcode in a PICT file that triggers a stack-based buffer overflow.
